This experimental study aims to investigate the dynamic properties of the timber shear wall structures with eccentricity. All the specimens were one-story system, having the wall layout arrangements so that the eccentricity ratio, Re may become 0 to 0.599. In addition, the horizontal diaphragms had two specifications with high and low shear stiffness. These dynamic properties were examined by shaking table tests. Through these experiments, the following result were obtained. 1) The first natural frequencies of the each specimens were so decreased as to increase Re. 2) Distributions of seismic lateral force became trapezoidal or triangular, which were different one in static state (considered as rectangular distribution). 3) In serviceability state, shear stress concentration ratio in dynamic state were 14〜78% larger than static theoretical value. 4) In ultimate limit state, shear stress concentration ratio in dynamic state were smaller than one in serviceability state.
